ilo (L7/Z whom, it may concern:

Beit known that I, SAMUEL GRAY, of I-Iarrisburg, in the county ofDauphin and State of Pennsylvania, have invented certain new and usefulImprovements in Buttons, of which the following is a specification.

This invention relates to certain new and useful improvements incollar-buttons.

vide a button which will be easily extended in order that its head maybe passed more easily through a series of buttonholes and to form thebutton in such a manner that the head may be moved in the same plane asthe shank or stem, so that as the head is pushed through a heavy collaror collar-band most if not all of the strain will be removed from thepivotal connection between the head and the shank or stem.

My invention therefore consists of a button of these characteristics,and the invention will be now more particularly hereinafter describedand then definitely claimed.

In the accompanying drawings, which show the preferable embodiment of myinvention, Figure 1 is a perspective view of my new button. Fig. 2 and 3are vertical sections with the head in different positions. Fig. 2a is ahorizontal section through the line 2a 2a, and Fig. 2b is a similarsection through the line 2b 2b, of Fig. 2.

Fig. 5 is a section of the head, taken at right angles to that shown inFigs. 2 and 3. Fig. 6 is a bottom plan of the head, the shank or stembeing shown in section. Fig. 7 is a perspective view of the shank afterit is crimped.

Referring now to the details of the drawings by numerals, l designatesthe shank of my new button, which is secured to or formed on the base 2in any desired manner. The shank is of course provided with a centralaperture or opening 3, and within this opening is located the stem 5,which is extensible or telescopes in and out of the shank. In order topermit this stem to be extensible and at the same time to prevent itfrom being entirely withdrawn from the shank, the shank and stem areformed in the special manner indicated in my drawings. As thereillustrated it will be observed that the lower part 6 of the shank (seeparticularly Fig. 4) is substantially oval shape, while the remainder ofthe shank has a central groove on each side and is thus shaped incross-section something like a figure 8. When the shank lis Fig. 4 is aperspective view of all of the parts detached.

first made, it is of the same shape as the lower portion of the stem. Inother words, it also is oval shape and is of that shape for its entirelength; but after thestem 5 is placed within the shank 1 the upperportion 8 -of the latter is crimped by any suitable machine, so i. thatsaid upper part is also in cross-section f, the same shape as the upperpart of the stem The objects of the invention are to pro- 5. Figs. 2aand 2b show the shape of the upper and lower portions, respectively, ofthe g stem and its shank after they are secured together. Inasmuch asthe shank 1 is made of somewhat springy metal, after its upper portionhas been shaped by a proper machine it hugs the stem 5 with suflicientresiliency to maintain any position to which it is moved in the shank.The purpose of making the lower part 6 of the stem of differentconfiguration from the upper part and also of forming the shank in thesame manner'is that the crimped portion of the shank forms a stop forthe uncrimped portion of the stem, and thus prevents the stem from beingwithdrawn entirely from said shank. This is very clearly shown in eachof Figs. 2 and 3.

The upper extremity of the stem 5 is formed with the usual lugs 9 and10, and above them and on top of the extremity of the stem is formed asmall projection 12. Instead of securin these lugs 9 and 10 directly toa pivotedead or to a piece secured thereto I employ a disk 15, formedwith a radial slot 16 of substantially the width of the extremity of theshank 5, and the central portion of this disk is Ypunched downward, thusforming two pockets or sockets 17 and 18, (see Fig. 6,) in which thelugs 9 and 10 of the stem find a bearing. Placed immediately over thedisk 15 is a second disk 20, formed with a T-shaped slot 21therein,which disk acts as a filler and yet permits the free movement ofthe parts on the lugs 9 and 10. There is yet one more disk 23 locatedover the disk 20; but this disk is merely formed with an integraltongue, with which coacts the small projection 12, formed on the top ofthe upper extremity of the stem 5. Around all of these parts is theinclosing cap or head 25, which before being placed in position is anordinary cup-shaped cap with a recess 26 in its vertical flange, asclearly illustrated in Fig. 4. After this cap is placed over the IOOother described parts the lower edge 28 of the IIO ment but a pivotalmovement on the lugs 9 and 10. The special purpose of cutting away theflange of the head to form the recess 26 and of forming the openings inthe disks 20 and 16 is to make it possible when the head is turned inthe position to be projected through a buttonhole for the head and stemto be in the Same vertical plane, as illus trated in Fig.` 3. When inthis position, pressure against a collar causes the stem to pass intothe shank until the head rests against the shank, (see Fig. 3,) when allof the strain caused by jamming the head through several buttonholes istransmitted in a vertical line to the stem and shank, and there istherefore no strain on the pivotal joint. I deem this ofgreatimportance.

What I claim as new is 1. In abutton, the combination with a shank andstem shaped to slide one within the other, the outer member having itsupper part crimped or formed of irregular contour, and the opposingmember having its end formed of smooth or regular contour, whereby oneacts to prevent the complete withdrawal ofthe other, when extended,substantially as described.

2. In a button, the combination of a shank and stem shaped to slidefrictionally one within the other, the outer member having a portionlongitudinally crimped or formed of irregular contour, and the opposingmember having a portion also similarly longitudinally crimped or formedof irregular contour, substantially as described.

3. In a button, the combination of a shank and stem shaped to slide onewithin the other, the outer member having its upper portion only crimpedor formed of irregular contour and its lower portion formed of regularcontour, and the opposing member having its upper portion crimped orformed of irregular contour and its end formed of smooth or regularcontour, substantially as described.

4. In a button, the combination of a shank and stem shaped to slidefrictionally one within the other, the outer member having a portionlongitudinally crimped or formed of irregular contour, and the opposingmember having a portion also similarly longitudinally crimped or formedof irregular contour, a head pivoted to the extensible portion, andhaving a recess permitting it to move, when the parts are extended, inalinement with the shank so as to rest thereupon, substantially asdescribed.

Signed by me at Harrisburg, Pennsylvania, this 7th day of February,1905.
